WebMass spectrometry (MS) has been widely used in the molecular mass determination and the structural analysis of organic molecules. Electrospray ionization, matrix-assisted laser desorption ionization (MALDI), and development in the instrumentation made MS an effective tool in polymer and biomolecular analysis. Together with these advances, MS is ... Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as … Ver más In 1886, Eugen Goldstein observed rays in gas discharges under low pressure that traveled away from the anode and through channels in a perforated cathode, opposite to the direction of negatively charged cathode rays (which … Ver más Mass analyzers separate the ions according to their mass-to-charge ratio. The following two laws govern the dynamics of charged … Ver más The final element of the mass spectrometer is the detector. The detector records either the charge induced or the current produced when an ion passes by or hits a surface. In a … Ver más When a specific combination of source, analyzer, and detector becomes conventional in practice, a compound acronym may arise to designate it succinctly. One example is MALDI-TOF, which refers to a combination of a matrix-assisted laser desorption/ionization Ver más A mass spectrometer consists of three components: an ion source, a mass analyzer, and a detector. The ionizer converts a portion of … Ver más The ion source is the part of the mass spectrometer that ionizes the material under analysis (the analyte). The ions are then transported by magnetic or electric fields to … Ver más A tandem mass spectrometer is one capable of multiple rounds of mass spectrometry, usually separated by some form of molecule fragmentation. For example, one mass analyzer can isolate one peptide from many entering a mass spectrometer. A … Ver más
